What is correct

Options

A. Bryophytes are vascular cryptogams
B. Pteridophytes are homogenous group of tracheophytes
C. Cordaitales grow in gymnosperm forests naked seeds.
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Bryophytes**:
- Bryophytes are non-vascular plants. They do not possess a vascular system (xylem and phloem) which is characteristic of higher plants.
- Therefore, the statement "Bryophytes are vascular cryptogams" is incorrect.

2. **Analyzing Pteridophytes**:
- Pteridophytes are known as vascular cryptogams and are characterized by their ability to produce spores.
- They are not a homogeneous group; rather, they are heterogeneous, meaning they consist of various types of plants.
- Thus, the statement "Pteridophytes are homogeneous group of tracheophytes" is also incorrect.

3. **Examining Chordatails**:
- The term "Chordatails" seems to be a misspelling or misinterpretation. If it refers to "Gymnosperms," these plants do produce naked seeds.
- However, the statement implies that they grow in angiosperm forests, which is incorrect as angiosperms are flowering plants that produce seeds enclosed in fruits, unlike gymnosperms that have naked seeds.

4. **Conclusion**:
- Since all the provided options (A, B, and C) are incorrect, the only correct answer is option D: "None of these."

**Final Answer**: D. None of these.
